JUST wallet

What is JUST (JST)?

JST is the governance and utility token of the JUST ecosystem on TRON, a group of DeFi protocols built around two products: JustLend DAO, a lending market where users deposit and borrow TRON assets at rates set algorithmically from supply and demand, and JustStables, where users lock TRX as collateral to mint the USDJ stablecoin. In both, JST is the token that steers the system. Holders vote on parameters such as collateral ratios, supported assets and rate models, and JST is also the token in which stability fees on USDJ positions are settled. Governance participation typically means locking JST into the protocol, which produces a wrapped representation (WJST) that carries the voting weight; the JST you keep in a wallet is the plain, unlocked token.

What holding JST looks like in practice

JST is a TRC-20 token, so it lives at a regular TRON address. It has no fee of its own: every transfer consumes TRON energy and bandwidth, and if the address has no staked TRX to cover that, the network burns a small amount of TRX from the same address instead. A JST balance with zero TRX next to it can be viewed but not moved, so keeping some TRX alongside is part of holding this asset. There is no rebase or automatic balance change in the token itself; the balance only moves when a transfer is signed.

A governance token tends to sit still for long stretches between votes, and that is exactly the kind of holding where the private key matters more than transaction speed. In Tangem the key for the TRON address is created inside the card's chip and never leaves it, and the backup is a second identical card rather than a seed phrase written on paper. For a JST position that you revisit rarely and want to find intact each time, that arrangement fits the way the token is actually used.
